My invention relates to railroad rolling stockand comprises a lubricator adapted vfor use in M. C. B. journal boxes `for forcing the lubricant from a reservoir below the "journal I up to .thesurface ofjtlie latter.

The objects oi' my invention are tofprovide a simple .economical lubricator whichfmay be inserted in the standard journal 'box without any Aadditions or. changes tothel latter which will accommodate variations inthe height ot' the journal due to differences in sizes or -to wear on the `journal brasses and which will'permitthe journal'box'togbe jacked up whenremoval of the brasses or their wedges is desired.

ln `the yaccompanying drawings which illustrate a selected embodimentof my invention,` f V i Figure 1 is a fragmentary longitudinal section through a journal `and journal box` with my lubricator applied thereto. Figure 2 is a transverse section on line 2 2 of Figure 1. `r i Figure 3 is a sectionshowing.aslightly modified form of :the lubricator delivery member. In the drawings. thebottomgof the journal box is indicated at 1 and the lower portion ot the. -journalis indicated aty 2. The jour- 0 nal is providedwit-h a collar `3, the Vinner' `surface ot which is engaged by a pump yoperating rod Llv lslidably mounted insa lubricator member 5 and vieldingly held in yits outer collar engaging position by a coil spring 6.

The lubricator body is preferably made in two parts, the upper member 5 being telescopingly mounted upon the lower member 7 which is adapted to be seated upon the bottom of the journal box. The outer periphery of member 5l slidingly engages the Linner periphery of member 7 andcoil springs 8 yieldingly thrust these two members apart, the separating movement being limited by the engagement of pins 9 in the walls of member 7 with the ends of recesses 10 in member 5.

The device is narrow and is maintained in position in box 1 immediately under the axis of the journal by means of a perforated sheet metal plate 11 which fits around mem` ber 7 and engagesthe sides and ends of the journal box. This member may also be used to support waste packing it it is found desirable to use thesame with my lubricator.

The lower member 7 of the lubricator comprises a pump cylinder 12 and an upwardly extending barrel 13.y A horizontal plunger 14 is lpositioned in cylinder "1'2`and may '1nclude ktheball check shown or the flop valve Construction described invmy copending applicationSerial Number .57 8,068. A vertical `pinfl at the outer-end of `plunger 14 is y slidmgly engaged by a sleeve 16 in rod 4.

deliveryelement 171isinsertedin barrel 13 and extends upwardly therefrom to the face of the journa'hhavng' an extended bearingglSlagainst the flatter.4 The uppergportion of rthis element is'supported upon a suitable seat. on member 5 and afspring V19 compressed'lbetweena pin20 in -member 17 and a check valve21 seatedin the lower end off barrel 13 immediately over the ,pump-cyl-v inder cooperates with springsft to insure an operating position of member 17. p

In Figure 3 I show a modified construction of the pump discharge elements in which the journalfengaging element 22 is re? movable from the sleeve 23 which slides in member 7. This permits replacement of this part when worn or when a different sized journal is tobe accommodated. "Hence unnecessary duplication of parts in stocking thelubricator is eliminated. g" y f #It is apparent from an inspection offthis construction that the upper member containyingthe contact rod and its return spring'and seatingthe ,delivery element 17 is movable as la unit to and from the lower member containing the pumpk plunger vand including a discharge chamber with a check valve. 'These twomembers although movable relativeto each other, form an enclosure which protects the operating parts andthe assembly of these members is such that the journal and journal box may be moved relative to each other as before indicated withoutv as are includedin the scope of the appended claims.

I claim: i y v1. rIn a. lubricator, a body memberhaving a part adapted to be seated in a journal box and provided with a horizontally' reciprocating'pump plunger, said member having anothergpart telescopingly assembled with said first-mentioed part and provided with horizontally reciprocating plunger operating means. f

, ed to rest upon the bottomof the box and comprising a pump cylinder and discharge barrel, an upper one-piece member having a sliding lit with said lower member and comprising an operating rod bearing and a delivery element support, a plunger in said cylinder, a journal engaging delivery element telescopingly mounted on said barrel, a journal engaging` rod mounted in said bearing, a rodreturn spring seated in the inner end of said bearing, a telescoping connection between said rod and said plunger, and yield* ing means supporting said upper member on said lower member.

Ll. In a lubricator, a horizontal cylinder and a vertical outlet for said cylinder, a delivery element slidable in said outlet, a plunger reciprocating in said cylinder, a vertical pin onfthe end of said plunger, a horizontal operating rod locatedv above said plunger, and avertical sleeve for said pin on .said rod said sleeve and pin forming a vertical adjustable connection between said plunger and rod. j

5. In combination, a railway journal box, an axle journaled therein and provided with a collar, luidvlubricant in said box, telescoping lubricator elements positioned under the axis of said journal and provided with a pump yextending below the surface of the lubricatorand including a horizontal reciption.

6. In a journal lubricator, a bodyadapted to rest upon the bottom of a journal boxand haying vertical walls, an upper member engaging said walls and slidable vertically thereon, a horizontally reciprocating pump piston on said body, a horizontally reciprocating contact rod on said member, and a telescoping connection betweensaid piston and rod. 'i y 7. In a journal lubricator, a body adapted to rest upon the body of the journal box, an upper member spring-supported on said body at spaced points,fa horizontally extending pump and piston in the lower por.- tion ot said body and a horizontally movable operating ,rod4 in said .upper member, and a connection between said piston and rod comprising interengaging members slidable vertically on each other but held against rela'- tive horizontal movement. j

8. VIn a lubricator for railway journal -boxes abody including a pump4 cylinder and a lubricant discharge passage, a member vertically telescoping with said body and having a lubricant delivery passage, an element on said member movable horizontally of said body to operate said pump, springs thrusting said body and member apart, and interengaging surfaces on said body and member for limiting the separating movements of the same.

Initestimony whereof I hereunto ax my signature this 6th day of July, 1922.
